MULTIPLE-COUNTER CASH-REGISTER.

Application filed August 31, 1912.

of separate totalizers are provided for ai-cumulating the grand totals of the amounts of all similar transactions and H1 addition two sets ol clerks" individual totalizers are supplied one set for accumulating the individual clerks cash sales and the other for accumulating the individual clerks received on account transactions. Incidental to this provision and arrangement of totalizers, novel selecting meel'ianisin for them has been developed which provides for throwing into enga ement with the actuators the desired clerk's individual cash totalizer along with the throwing in of the totalizer which accumulates a grand total of all cash transactions, and for throwing in of the desired clerks individual received on account totalizer whenever the totalizer for accumulating a. grand total of all received on account" transactions is connected with the actuators. This is accomplished broadly by the use of a selective controlling bar for the sets of totalizers which is difl'erentially moved when cash, received on account or other transactions are entered, the extent of which movement determines whether either of the clerks individual sets of totalizers will be engaged with the actuators along with the engagement of the transaction set and in case one of these sets is to he also actuated, whether it is the chat. s individual cash, or the clerks individual received on account set.

To provide an improved type of differential mechanism was also an object of this invention. and such is herein disclosed in a key controlled elnbodinu-nit though its adaptation to other types of control. such as lever control, will be readily apparent. Its structural novelty resides in a link. toggle or equivalent connection" between a driving Specification of Letters Patent.

member having a constant movement at each operation, and a member adapted to be given differential movement thereby, such that normally a positive driving connection between these members is provided by the end of the toggle or link engaging the driven member, but which driving connections may be rendered ineffective, at different points in the movement of the driving member by freeing the end of the toggle or link which engages the driven member so as to permit further movement of the driving member independent of the driven member, the freed end of the toggle or link normally engaging the driven member, deflecting from its point of driving engagement with the driven member (hiring such further move ment of the driving member.

This invention further presents a novel and improved form of transfer mechanism for taking care of the necessary carries between wheels of lower order to those of next higher. This novel form does not provide separate transferring mechanisms for all of the totalizers but in the arrangement shown only the elements of one totalizer in each group of totalizers are in operative alinement with the common transfer mechanisms for that group at one time. Long teeth on the totalizer wheels when the lat ter pass from nine to zero, trip their transfer mechanism allowing the transfer pawls of the latter to recede and engage hehind one of the teeth on the wheels after which the transfer mechanism with its pawl is restored to normal position by the oscillation of a f "zone.

In the machine of this invention all of the tota-lizers may be reset at Zero or turned. to zero and read and then returned to their original position by operations of the machine which result in the printing of the amounts standin on the totalizers prior to the operations. .0 provide for such operations of the machine it is provided not only with the usual amount, transaction. and clerks banks of keys, but also with a special read and reset bank of keys which in connection with the clerks and transaction banks of keys determines the totalizer to be read or reset at Zero. This read and reset bank of keys controls the differential movement of a read and reset counter selecting bar the different positions of which in combination with the different positions of the selector bar for the transaction bank of keys above mentioned, provides for the reading or resetting of any of the amount counters of the machine. The selector bar controlled from the read. and reset bank of keys is necessary because of the fact that the selector bar used in entering transactions provides for throwing in engagement with the actuators both the transaction set of totalizers and one or the other of the sets of clerks individual totalizers in some operations of the machine. This would not be permissible in reading or resetting operations so the read and reset selector bar serves to prevent more than one totalizer being engaged with the actuators at any time in such operatioi'is. These read and reset keys also control the time of engagement of the totalizers with the actuators by disconnecting an adding cam normally in position to engage the totalizers with the actuators on the return stroke of the latter, and connecting either a read or reset cam for controlling the time of engagement of the totalizer with the actuators.

Further objects of the invention are to provide in the printing mechanism an improved construction for preventing the printing of ciphers by the type segments of higher order than those indicating other amount characters, and to provide for the printing of ciphers by those type carriers of lower order than the highest indicating other than zero when such lower order type carriers are not adjusted to print characters other'than zero. In the machine of this invention, this is provided for by mounting the type characters on bars pivotally supported and carried by differentially adjustable segments, which bars are free to yield against the printing impression of the platen when they are in zero position, so as to prevent the taking of printing impressions therefrom, but which are adapted to be supported against such yielding whenever any type segment of higher order is moved to other than zero position. Projections 011 the pivoted type bars engage beneath the type bars of next lower order and pins on the segments engage beneath the type bars of the segments of next lower order whereby. when a segment is moved from zero position the one next higher standing at zero, its type bar will be supported by the pin projecting from the next higher segment and this supported bar through the connection between the pivoted bars thus supports all of those of lower order.

A still further object of this invention was to provide an improved form of record strip feeding mechanism by which in operation the record strip is reversely fed to a. slight extent to position it for receiving a printing impression after which impression it. is fed in a forward direction to an extent greater than that of its reverse feed before printing, thus taking care of the necessary general feed in a forward direction. In the mechanism herein disclosed these feeding movements of the record strip are accomplished by rotating the supply roll for the record strip to pull the latter rearwardly previous to printing and rotating the receiving roll after such printing to draw the paper forwardly the latter roll bein rotated in this movement to an extent su cient to pull the paper forward farther than it was drawn reversely by the supply roll. A common oscillating member is provided which is connected by links with pawl carrying frames for rotating the rolls and thus serves to rotate the latter at desired times. The link for the receiving roll is connected with the oscillating member at a point farther from the axis of the latter than is the point of connection of the other link, thus providing for a greater feed of the strip by the receiving roll than by the supply roll. The other ends of the links are connected with the pawl carrying frames by pins working in slots in the frames, which pins are also adapted to rest on the record material on the rolls the amount of which thereon serves to control their extent of rota-- tion thus tending to equalize the feed of the record strip which would otherwise vary with the diameter of the rolls.

The machine of this invention also embodies an improved construction for setting the indicator elements in accordance with the differential setting of their actuators which improved construction employs arms mounted for oscillation on the driving member for the actuators, and rigid with arms having cam slots which slidably engage over stationary members so that as the arms having the cam slots are carried with the driving member they will cause the first mentioned arms to engage and serve to normally position the intermediate. portions of links connecting the indicating elements with their actuators.

The invention also includes a novel construction by which depression of a clerks key serves to unlock the machine for operation and through which near the end of the operation, depressed keys are released. In the form disclosed for ZICXEOITIPllSlllDg these results the cl'erks detent plate is provided with a notch normally out of alinement with a pawl rigidly carried by an oscillatory shaft. This shaft also carries an arm connecting with a spring controlled link which also connects with machine locking mechanism. WVhen the clerks detent plate is raised by de n'ession of a. key its notch comes opposite its coacting pawl thus permitting the link to move under force of its spring, to unlock the machine, the accompanied rotation of the oscillatory shaft also serving to
